Castellation rainscreen cladding: precision in every façade

Designed to bring buildings to life

Modern architecture asks more of a façade than weather protection. Architects want elevations with identity and depth that still deliver the technical performance expected of a modern building envelope. That is why we developed the EG Castellation System.

Narrow, Wide, Varied, and Step profiles give architects the freedom to create dynamic elevations with a bespoke appearance. Across commercial offices, education, residential developments, and public buildings, the system turns flat façades into architectural statements. Every profile is formed using precision bending technology for consistency across each panel and elevation.

Performance engineered from experience

Design is only one part of the story. Our rainscreen systems are independently tested in accordance with CWCT guidelines and built to meet the demands of modern construction. The EG Castellation System offers:

• Excellent weather protection
• Ventilated façade performance
• Enhanced durability and longevity
• A1 and A2 fire-rated options
• Lightweight construction
• Reduced maintenance requirements

The ventilated cavity behind the façade manages moisture effectively and improves the overall performance of the building envelope.

Precision manufacturing, family values

As a family-run business, we believe reputation is earned through consistency, quality, and trust. Those principles have guided every project we have delivered for over 65 years.

Every EG façade solution reflects that commitment, from initial design support through to manufacturing, packaging, and delivery. We understand the pressures architects and contractors face, so we focus on systems that look impressive while staying practical to install and dependable on site. It is why Eltherington systems continue to be specified on major architectural projects across the UK.

Supporting architects from concept to completion

Architecture is increasingly collaborative, and we see ourselves as part of the design journey. Through the EG brand, architects, specifiers, and contractors can draw on:

• Technical design assistance
• NBS specification support
• CWCT tested systems
• Material and finish guidance
• Fire performance support
• Engineering collaboration and project support

The system is available in a wide range of materials and finishes, including PPC aluminium, anodised, Corten, Rimex, and pre-painted options, giving designers creative freedom alongside technical compliance.

Sustainability built into the system

Aluminium remains one of our key materials thanks to its strength, durability, and recyclability. Combined with lightweight construction and the thermal benefits of a ventilated façade, EG rainscreen solutions help deliver more efficient modern buildings.

Looking ahead

The industry continues to evolve, but our approach stays the same: precision engineering, trusted partnerships, and quality without compromise. The EG brand is the next chapter for Eltherington Group, built on over 65 years of delivering architectural solutions that perform as well as they look.
